CHARLESTON, West Virginia (CFP) — U.S. Senator Bernie Sanders of Vermont easily won the Democratic presidential primary in West Virginia, notching a rare victory in the South.

Sanders took 51.4 percent of the vote in Mountaineer State, compared to just 35.9 percent for Hillary Clinton. On the Republican ballot, Donald Trump–now unopposed for the nomination–scored an easy victory, taking 77 percent in the May 10 vote.

A Republican hasn’t won the governorship in West Virginia since 1996. However, the state’s recent GOP trend, which including capturing the state legislature in 2014, has given Republicans high hopes for taking the state’s top office.

But they will have to get past the deep pockets of Justice, a billionaire farmer and coal mine owner who was a registered Republican until 2015. Justice has gotten the coveted endorsement of the politically powerful United Mine Workers of America and other labor groups., as well as conservative Democratic U.S. Senator Joe Manchin.

Sanders’ victory in West Virginia is just his second win in the South this primary season. With only Kentucky left to vote on May 17, Clinton has swept everything in the region except Oklahoma, most by wide margins.

Speaking to jubilant supporters in Salem, Oregon, as the results came in, Sanders pointedly noted that Clinton carried West Virginia by more than 40 points when she ran against Barack Obama in 2008

“West Virginia is a working class state and like many other states … in this country, working class people are hurting,” Sander said. “And what the people of West Virginia said tonight, and I believe the people of Oregon and Kentucky will say next week, is that we need an economy that works for all of the people, not just the 1 percent.”

Clinton was dogged by a remark she made in March that “we’re going to put a lot of coal miners and coal companies out of business,” which went over badly in coal-producing West Virginia. She later apologized for what she termed a “misstatement.”

Kentucky, the last Southern state left in the Democratic primary calendar, is also a coal-producing state. Both Sanders and Clinton have been campaigning hard in the Bluegrass State.

West Virginia was the final Southern stop for Republicans. Trump won every state in the region except for Oklahoma and Texas, which went to U.S. Senator Ted Cruz.
